ELECTROCHEMICAL ACCUMULATOR WITH PACKAGING COMPRISING AT LEAST ONE POLYARYLETHERKETONE (PAEK) SHEET, SHEET AND ASSOCIATED MANUFACTURING METHODS

摘要

The invention concerns a new flexible or rigid packaging for an electrochemical accumulator (A). The packaging contains at least one polyaryletherketone (PAEK) sheet, notably a polyetheretherketone (PEEK™) sheet. According to a preferred embodiment, a polyaryletherketone (PAEK) sheet incorporates within it at least one metal stud constituting one of the poles of the accumulator. The packaging is useful for the packaging of lithium-ion accumulators.

主权项

1: An electrochemical accumulator comprising an electrochemical cell comprising an anode and a cathode on opposite sides of an electrolyte, a first current collector comprising a first strip, which is connected to the anode, and a second current collector comprising a second strip, which is connected to the cathode, and a packaging, which contains the electrochemical cell in a sealed fashion, whilst being traversed by a proportion of the first and second strips forming poles which extend in the plane of the electrochemical cell,
wherein the packaging comprises multiple polyaryletherketone (PAEK) sheets attached to one another at their periphery.
